Archaeology within a unified science of cultural evolution - Prof. Alex Mesoudi

[@parallelThreads]

Prof. Mesoudi, please repeat the sizing experiment with students formally trained in visual arts; especially sculpture students, but also including arts majors who have received a classical training in drawing and painting. When I was in middle school and again in high school, I attended magnet programs as an art student. I received approximately 3 hours a day in classical art instruction for approximately 6 years. I was jarred when you said that normal people cannot perceive size differences less than 3% as I could easily tell the difference in sizes between the examples shown. Perhaps, ancient knappers would have received equivalent training in size and shape perception from a young age and would consistently and significantly outperform average modern adults in this regard. This might explain the significant difference in observed variation noted at 27:00 in your lecture.
